To all/ whom it may concern:

wealth of Massachusetts, have invented certain new and useful"Improvements iin I Trouble-Lamps, of which the following is a:

specification.

This invention relates to .dEIXlPS and particularly to a portable lampof the class: These lam;ps; which are primarily intended for use aboutautomobiles are usually electric lamps con-i nected'by a long flexibleswitch cord which permits the "lamp :to .be used on any :part of knownas trouble lamps.

the car. *I-Ieretdfore these lamps have been simply electric bulbs andwhile Wery useful} they have "been of "only limited convenience onaccount of the *difiiculty of handling the light in the many di-fierentparts of a car:

i "the clamps 9 and 10 are interlocked fby 1a 275 11p .14 struck downfrom the clamp 9 and where illumination is needed.

provide a lamp which will not only have an increased convenienceunder-ordinary use: but which will have possibilities of variedadditional uses and particularly to i-fit the possibility :of -.asemi-permanent attachment 1 at such a convenient place :as the roberail? in the :tonneau iior the illumination of the rear seat and-theTea-r steps.

The construction and-operati on 101 my *device will be more fullydescribed in the M.

In the drawmgs, trative embodiment a construction "which not onlyclearly illustrates any invention but is in itself a to m proven to beef:the great- 7 Y cosntruction.

est utility in p actical use.

In the drawings, Figure 1 "is a side-view of my. lamp. Fig. 2 is a planView showing the lamp mounted on a vsection of the robe Fig. 3 is :apartial central section rail.

' Figs. 4 and 5 are details of the-clamp member and Fig. 6 is amodification of the Flight,

i the bar 30 so as to disengage it from the focusing adjustment.

I have shown asan illusvIn the for-m of my invention shown, *1

provide a-circu' lar frame 1 having tan-arched extension formed with abearing B. The upper part of the ibeariin 3 is hollowed out at 3 430afford a :th'um hold, whilesat its lower part it is extended :at 4 inthe form of a trigger shaped khoo'k adapted zto ibe en aged by theforefinger. At the lower en 10f the intone 1 is ormed .a -.-stub T5 inWllldh the threaded stem 6 {is set. 0n fl1is :stem is screwed ahand'lelfhavingaxthreaded ":66 cup A clamping member "is iprowided which is runon the stem 6 and compresses against the stub 5 by 'the handle as it isscrewed up. Thee-lamp which is :adaptedto engage a robe rail R or zanyother com 7'0 venient bar or rod, consists of two members59 and 10 whichare provided with the stem receiving :openin 1 1 .and'with clamp in'gjaws '12 and 13. he opposite ends of entering the slot "15 in the clamp10. tl 'ithjin the bearing 3 is threaded ra wtu'biilar sleeve .16 on themner end of 'n h idh is a bayonet joint 17 adapted to receive :an incan-80 for focusing the light at any desired dis- .85

tnnce. 'The (reflector shell 21 i is :set within the frames 1 and "2 andat its outer edge is formed with a arim 22 in which thelens is set andheld in place by :a ring-23. who inner :end of the reflector :212has'atubu- .90

lar extension 24 which is -engaged ;hy a set member 2 just in advance ofthe thumb h #3 The switch wire26 centers tthnough t e .16 is suitablyconnecte with the.--socket :27 which makes proper electric contact inthe usual manner, with the filament-connections of the bulb 1'8. '1"have indicated at 2:8 the switch plug which .is engaged'by a bridgegpiece i3 1. llhe s05 adjustment 0 "the light is secured in thismodification by depressingfithe end 30 of knob 19 and passin through thesleeve :93

which may be of any "desired 10.0

bridge piece 31 whereupon the tube 16 may" he slid backward or forwardto secure the desired adjustment.

The lamp may be'used as an ordinary hand lamp either by engaging thefore finger in the hook 4: with the'thumb on the hollowed out part 3 orit may be held by,

- its handle. ,The hook 4-furthermore can be used to hang up the lamp inany part of the engine or car and when so suspended the handle whichextends belowthe level of the hook supports the lamp and prevents it.

- from tipping down or falling in. Forsemican be kept in convenient andaccessible position.

Various other modifications may obviously be made in the operation andconstruction of my device all without departing from the spirit of myinvention if within the limits of the appended claims.

What I therefore claim and desire to secure by Letters Patent is:

' 1. A lamp of the class described comprissaid frame,"a downwardlyturned hook on said'fra'm'e, said frame having an oppositely "disposedthumb bearing.

2. A lamp of the class described comprising a frame, a source of lightmounted therein, a" downwardly projecting hook on said frame, and adepending handle in advance of said hook level thereof. y

3.'A lamp of the class"describedcomprising an open frame, a reflectorsupported in and extending below the presence ing a frame, a source "oflight mounted I therein, a downwardly projecting hook on said frame; a'depending handle in advance of said hook and extending below the levelthereof and a swivel clamp adjustably mounted on said handle andbelowthe level .of said hook.

4:. A lamp of the class described compris- .ing a frame, a source oflight mounted there1n,and a clamp swiveled to said frame adapted forclamping engagement with a support, and means for tightening saidjaws.

6. A lamp of the class described comprising a frame, a source of lightmounted therein, a handle, a device operatlvely connecting said handleand frame, and aclamping member swiveled to said connectlng device. I

7. A lamp of the'class described comprising a frame, a source of lightmounted therein, a handle, a threaded stem operatively connecting saidhandle and frame, and a clamping member swiveled tosaid stem.

8. A lamp of the class described comprising a frame, a: source of lightmounted therein, a handle, a threaded stem operatively connectingsaidhandle and frame, and a clamping. membercomprising interlockedengaging jaws swiveled tosaid stem.

9. A lam of the class described comprising a frame, a source of lightmounted therein, a handle, a threaded stem operatively connecting saidhandle and frame, and a clamping member comprising a pair of oppositelycurved jaws swiveled to said stem. In testimony whereof I afiix mysignature of two witnesses. Y THURBUR- F. RUSSELL. Witnesses VICTORIALOWDEN, MARION C. HoBBs.-
